The question tells you to have the overridden function return the person's name as Dr. "lastName". In your case you were hard coding your name in the return. All you need to do is return "Dr. (lastName)".

class Person {
    let firstName: String
    let lastName: String

    init(firstName: String, lastName: String) {
        self.firstName = firstName
        self.lastName = lastName
    }

    func getFullName() -> String {
        return "\(firstName) \(lastName)"
    }
}

class Doctor: Person {
    override func getFullName() -> String {
        return "Dr. \(lastName) "
    }

}
let someDoctor = Doctor(firstName: "HAitham", lastName: "Alam")
